Mathalytics Hockey

Hockey, by the numbers.

Who's actually good, who's just lucky, and how you can tell. Expected goals, shot maps and the NHL's own tracking data, explained the way you'd explain it to a buddy at the bar.

What this is

Our own xG model

Every unblocked shot gets an expected-goals value from a model trained on ten seasons of NHL shots (over a million of them): distance, angle, rebounds, rushes, strength and more. When a number is a model's best guess, we say so.

Tracking data, redrawn

The NHL's EDGE puck and player tracking, rebuilt as little replays so you can see what actually happened on the play, not just the box score.

No hot takes

Every video starts with a question we actually wanted answered, then goes and finds out. No predictions, no betting picks, no highlight packages.
